Galvanized Steel Wire for Optical Fiber Cables - High-quality Suppliers and Factory in China
Product Advantage
The function of the stiffener is to improve the tensile performance of the cable. Steel wire as a strengthening part, its cost, processing technology and performance indicators are easy to meet the production needs of optical cable. In addition, the steel wire of optical fiber and cable is not easy to rust and will not cause hydrogen damage. Optical cable steel wire needs to be treated, the cost of stainless steel wire is higher, the use of galvanized steel wire not only ensures the process requirements, but also reduces the cost.

Frequently Asked Questions
What is the main function of the stiffener in the optical cable?
The primary function of the stiffener is to significantly improve the tensile performance of the optical cable, ensuring it can withstand physical stress during installation and operation.
Why is steel wire commonly used as a strengthening part?
Steel wire is chosen because its cost, processing technology, and performance indicators easily meet the specific production needs and quality standards required for optical cables.
Does the steel wire inside the optical fiber cable rust easily?
No, the steel wire used in optical fiber cables is specially treated so it is not easy to rust. Furthermore, it will not cause hydrogen damage to the fibers.
Why choose galvanized steel wire over stainless steel wire?
While both require treatment, the cost of stainless steel wire is significantly higher. Galvanized steel wire is preferred because it guarantees the strict process requirements while effectively reducing production costs.
What is the typical strength range for the galvanized steel wire?
Depending on the specific diameter of the wire (ranging from 0.45mm to 2.77mm), the required strength is generally between 1270 MPA and 1770 MPA.
